Available in PDF, EPUB and Kindle. Book excerpt: A relatively large collection of fatigue-crack growth results for annealed Types 304 and 316 stainless steels over a wide range of temperature was processed and analyzed in a consistent way. Only data that satisfied the criteria of ASTM E647-82 was retained and used in the statistical treatments that followed. Linear least-squares regression equations and 95% confidence intervals were fitted through the results for each material/temperature set. The regression results (and their associated limits of validity) provide useful equations for the analysis of structural components. Overlap (or the lack of overlap) of the confidence intervals was employed as a criterion as to whether the results for Types 304 and 316 should be separated into discrete sets, and on this basis it was concluded that the two alloys should be treated separately. 38 references, 16 figures, 1 table.

This book was released on 1973 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: The resistance to fatigue crack growth of annealed stainless steels, Types 304, 316, 321, and 348, was determined at 77, 800, and 1100 F (25, 427, and 593 C). Crack growth rates were related to the stress intensity factor range (?K). With increase in temperature the rate of crack growth for a given (?K) increased. At room temperature the four steels had the same resistance to crack growth. However, at high temperatures crack growth became sensitive to the differences in composition and properties among the steels. At 1100 F (593 C), Type 348 steel had the greatest resistance to crack growth and Type 316 the lowest resistance. As a result, fatigue life was 3.4 times longer for Type 348 steel over Type 316 steel at this temperature. The characteristics of high-temperature fatigue crack growth were examined.

Available in PDF, EPUB and Kindle. Book excerpt: The effect of specimen size upon the fatigue-crack growth behavior of annealed AISI Type 304 stainless steel was studied at two stress ratios at an elevated temperature. The resulting data were examined in the light of the present ASTM size criterion (based upon monotonic yield stength) as well as a proposed criterion based upon the material flow strength. The flow stress criterion is considerably less restrictive than the present ASTM Criterion, and the results of this study indicate that the flow stress criterion is entirely appropriate for strain-hardening materials such as the austenitic stainless steels.

Available in PDF, EPUB and Kindle. Book excerpt: The research reported here is an investigation of the influence of the mechanically induced martensitic transformation on the fatigue crack growth rate in 304-type steels. The alloys 304L and 304LN were used to test the influence of composition, the testing temperatures 298 K and 77 K were used to study the influence of test temperature, and various load ratios (R) were used to determine the influence of the load ratio. It was found that decreasing the mechanical stability of the austenite by changing composition or lowering temperature decreases the fatigue crack growth rate. The R-ratio effect is more subtle. The fatigue crack growth rate increases with increasing R-ratio, even though this change increases the martensite transformation. Transformation-induced crack closure can explain the results in the threshold regime, but cannot explain the R-ratio effect at higher cyclic stress intensities. 26 refs., 6 figs.

This book was released on 2013-03-09 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by TPRC at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemina tion phases of the activity was transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we have concluded that it will be in the interest of all concerned if the printing and distribution of the volume were handled by a well-known publishing house to assure improved service and better communication. Hence, effective with this Volume 18, Masters Theses in the Pure and Applied Sciences will be disseminated on a worldwide basis by Plenum Publishing Corporation of New York. All back issues can also be ordered from Plenum. As we embark on this new partnership with Plenum, we also initiate a new venture in that this important annual reference work now covers Canadian universities as well as those in the United States. We are sure that this broader base will greatly enhance the value of these volumes.

Available in PDF, EPUB and Kindle. Book excerpt: Stainless steel is widely used in the industries nowadays due to their good properties of resistance to corrosion and rust. Due to its application in many industries, an analysis of fatigue crack growth was carried out to study the effect of stress ratio. The study of fatigue crack growth is important since fatigue has become a critical issue in industries that plague any structures that is subjected to cyclic and variable loading. A necessary analysis of fatigue crack growth need to be done to study the behaviour of fatigue crack growth. The effect of stress ratio on fatigue crack growth can affect the behavior of fatigue crack growth. In the project, three different stress ratios were used to investigate the effect of stress ratio towards crack growth. As the stress ratio increase, the stress intensity threshold and fracture toughness will decrease. This shows that an increasing stress ratio will lead to material failure. This happens when the stress intensity factor has entered the critical region where it exceeds the fracture toughness value. To remain the material unbroken or fail, the stress intensity factor value must not exceed the value of stress intensity threshold where below the stress intensity threshold value, the material remains stable. An analysis of fatigue crack growth was done using MSC software where the stress analysis is done using MSC PATRAN and MSC NASTRAN. After the results of stress analysis were obtained, the analysis of fatigue crack growth with different stress ratio was done using MSC FATIGUE software. Life prediction of the material is determined using Modified Paris Law equation of Fracture Mechanics. At certain level of stresses, below the endurance limit of the material, the effect of stress ratio does not affecting the life of the material. This is because the stress is not big enough to break the material.
